Tutorial Step 1: Download and install the Raspberry Pi Imager As part of this tutorial, we’ll be installing the Raspberry Pi Imager. This is written assuming you are using Windows 10 as the operating system on your laptop or desktop computer. Lastly, a Raspberry Pi, so you can boot the operating system.A SD card reader which is compatible with your computer.A micro-SD card, between 8 and 32 GB in size.In this post we’ll go through the process of downloading and installing the Raspberry Pi Imager, and then using it to flash a micro-SD card. Whether you want to try a new OS or go back to a clean install, there are a number of good reasons to reinstall and flash a new operating system to your Raspberry Pi. Step 2: Use Raspberry Pi Imager to flash an OS. Step 1: Download and install the Raspberry Pi Imager.If you need to format the card for use in Windows again, simply use the SD card formatter. This is because the Raspberry Pi images are Linux format, which is unviewable in Windows. When viewing the card on a Windows machine, it's normal that the card will appear to have less memory than it should e.g.Your SD card might be renamed to something like "BOOT", which is normal.That's it! Once the process is complete your new operating system image is ready to use. Hit yes, and the image will burn to your card. You'll get a warning message to confirm that you're happy to proceed. When you're happy that you have the correct image, and correct device, hit write. The last thing you want to do is overwrite your computer's hard drive! Win32 will pick up any removable media including SSD's. Now, insert your SD card into your laptop/computer and b rowse to your image file.īEFORE YOU HIT WRITE - Please make sure that you have selected the correct device. There's one more piece of software we need to burn our image - Win32 Disk Imager. IMG format.Īssuming that you have a nice clean SD card, we're now ready to copy your operating system image over! If required, you can now unzip your OSMC (or other) Raspberry Pi image. This means the file integrity has been validated and we can get to the next step! If the two codes match, you'll get the pop up "MD5 Check Sums are the same". Then browse to the downloaded file, and click calculate (it usually does this automatically). Unless your using the same download exactly, your Checksum will be different. For the OSMC image we're validating, this is:Ī09e11ec4d34dc992e9869997b69e570 (as shown above) I think you can probably guess what we do next! Copy the Checksum MD5 from the website into the box that says compare. Run winMD5Sum and you'll be rewarded with the following screen: Others are available, but this is the one we've had best results with. We now need to download and install winMD5Sum, a free and open source hash verification program. So, dowload your chosen OS, and move it to a place you can find it. If the file is zipped or compressed in some way, don't extract the file just yet! You will be validating the downloaded directly. In the image below, I've downloaded the latest OSMC image, and highlighted the checksum which we'll use to validate that image. We'll go through the Windows process here, as that's the system that we use. You can view a rundown of how to MD5 here. The process for validating is different for all operating systems. This isn't strictly necessary, but it's always good to double check these things! Not all, but most downloadable operating system disk images (.IMG) will have a Checksum (MD5) code that you can use to validate the image. The installation process is very easy, and we'll show you how! OSMC, RetroPie, RISC OS, and many others distribute their "bare" disk images, including BETA and latest iterations for download and installation direct onto an SD card for use on your Raspberry Pi. However, these aren't always the most up to date iterations of those software platforms. NOOBs is the Raspberry Pi Foundations New Out Of Box OS that has a small selection of operating systems for new users to choose from. So you've got your shiny new Raspberry Pi and want to try loading a "3rd party" or BETA operating system (OS) that aren't supported by the standard NOOBs installation.
